To all whom it may concern:

Be it known that I, Go'r'rrroLD L. LANGER, a citizen of the United States, residing in the city of Portland, county of Multnomah, and State of Oregon, have invented certain new and useful Improvements in Packaging- Machines, of which the following is a specication.

MyV invention relates to packaging machines, and more particularly to machines of the character shown and described in my pending application, filed January 5, 1916, Serial Number 70,461, and which machines are adapted to automatically weigh a predetermined amount ofmatter; to wrap the same, and to discharge the wrapped package into an open box, or carton, adapted to receive the same.

Among the salient objects of the present invention are,-to provide in a machine of the character referred to improved mechanism for weighing a predetermined amount of the matter to be wrapped and for discharging the same into the wrapping mechanism; to provide in combination therewith an im roved and simplified receiving and wrapping mechanism, comprising a revoluble whee -like structure provided with a series of receiving wrapping pockets into which wrapping paper and the matter to be wrap d are delivered, with successively positioned folding members to which said wheel carries said wrapping paper, and said matter, during its revolution, whereby the paper is folded about the matter as it is moved adjacent said several folding members, thus` eliminating the necessity for a complete set of folding members for each receiving pocket; to provide in a machine of the character referred to, improved means for compressing the wrapped matter and for delivering it to an open box, or carton, and, in general, to provide a simpleand practical automatic weighing and packaging machineV of the character referred to.

Inorder that others may understand my invention, I have illustrated one practical embodiment thereof in the. accompanying sheet of drawings, in which, j

Fig 17 shows an edge and outside face viewlv of one of the bottom end folding wings; anc

Fig. 18 shows side and edge views of a detai Referring now more in detail to the drawings, my invention as here illustrated comprises a base 1, and three upright frame members 2, 3 and 4. Rotatably mounted between the frame members 3 and 4, u on an axle 5, is a wheel-like structure 6, aving around its periphery a series of receiving wra ping pockets 6a, 6b, 6c, 6d, 6", 6, 6g and 6", tiere being eight of these pockets in the present construction, each open at its ends and at its outer side, said wheel structure being keyed to the shaft 5, as at 7, as is also a large driving gear 8, just inside of the frame member 3, said wheel structure 6, being turned intermittently an eighth of a revolution by means of said gear 8. Referring to Fig. 5, which shows a vertical sectional view, it will be seen that said Wheel structure turns within a surrounding bandlike inclosure 9, made as a part of the frame structure, and forms a closure for the outer open sides of the wrapping pockets, as said wheel structure with said pockets are revolved therein; said inclosure, however, being open at its upper side, as at 10, at which vpoint each of the wrapping pockets of the wheel structure 6, stops to receive a quantity of the matter to be wrapped, as clearly illustrated in Fig. 5.

The machine is power driven, as by means of a pulley 11, mounted on a shaft 12, shown in section in Fig. 1, in which figure, and also in Fig. 2, said driving pulley is omitted. Said shaft 12, has a beari'ng in the frame member 2, and `also in frame member 3, as will be clear from Figs. 2 and 3, and is provided immediately inside of frame member 2, with a loose pinion 13, having clutch teeth 14, onV its inner face, adapted to have intermittent driving engagement with a clutch 15, for throwing the main part of themachine into and out of driving connection with the shaft 12, and the pulle 11, said clutch being shown in detail in 4igs. 8, 9 and 10, and hereinafter more particularl described. A shaft 16, is mounted throng the upright frame lmembers2, 3 and 4, as clearly seen'vin Fig. 3, said shaft being provided onits end outside of frame member 2,

with a slide gear 17, and o-n the inside of said frame rmember 2,with a gear 18, in mesh-with the pinion 13,'seen' in Fig. 2. Said shaft 16, is also provided with slide gears 19 and 20, and at its opposite end, outside the frame member 4, with 'a double slide gear, the parts of which are designated,

' respectively, 21 and 22, kwhich parts are bolted together so as to bring their toothed portions and their smoothed portions in proper relative positions for operating gears hereinafter referred to. A third shaft 23, is mounted through the frame members 2 and 3, directly underneath the shaft 12. On the outer end of this shaft, is a gear 24, having two sliding,or locking faces 2,4a and 24",

said gear 24, being adapted to be intermittently turned and locked by the gear 17, which has a short series-of teeth, as at 17,

Y corresponding in number to the number of 'r vteeth on the Vopposite sides of the'locking faces 24a and 24h, of the gear 24, whereby as saidgear 17, revolves,it gives gear24, a half turn with each complete revolution it makes. Mounted on the inner end of the said shaft 23, inside the frame member 3, is a gear, or jinion 25, which is shown in dotted lines in ig. 2, and which pinion is directly behind the gear 23, shown in Fig. 1, and in mesh with the large gear 8, on the shaft 5, and by means of which the wheel structure 6, is driven.

I will now describe a clutch mechanism, shown in Figs. 8, 9 and 10, and by means of which the folding mechanisms and the principal operating parts of the machine are intermittently thrown into and out of driving connection with the main driving shaft 12, on which the pulley 11, is mounted. As hereinbefore stated, the pinion 13, with the clutch teeth 14, is loosely mounted on said shaft 12. Also mounted on said ,shaftrr 12, is a companion clutch member, or sleeve,

26, having clutch teeth 27, adapted to be i moved into and out of mesh with the clutch teeth 14, on the pinion 13, said clutch sleeve 26, being slidably secured-to the shaft'12, by means of a feather 28, andV normally moved into driving engagement with the pinion 13, by means of a spring 29,- on said shaft 12,l as clearly indicated in Figs. 2, 9 and 10. The lclutch sleeve 26, is supported in a bearing member 30, said bearing member being held in place on said sleeve 26, by means of anut 31, threaded `on to said bearing sleeve 26, as clearly `indicated in Fig. 10. y Said bearing member 3Q, is 'provided at its lower side with a guide sleeve 32, slidably mounted upon a shaft 33, hav-l CID .sin

34, is provided with a notch 37, in one side,

within which is adapted to seat'a trip lever 38, Whichi's normally drawn toward said plunger by means of a coiled spring 39, attached at its opposite end to a fixed pin 40,

set in the nut 31. The plunger 34, is provided With a rounded corner, as at 34a, and is adapted to be engaged by a fixed lcam block 41, mounted upon the inner face of the gear 18, whereby as said cam block 41, engages said plunger 34, it forces said plunger, togetherwith said bearing membery 30, and the clutch sleeve 26, awa fromk the clutch pinion 13, Fiof. 9, thus isengagingrfthe clutch teeth 2??, of the clutch sleeve 26, from the clutch teeth 14, on the inner face of the7^ pinion 13. Inasmuch as the clutch sleeve 26, is slidably `secured tothe. shaft 12, by means of the feather 28, it will be evident that when said parts are moved away'froni the pinion 13,A and out of mesh with. thel clutch teeth 14, as above stated, said pinion 13, and the large gear 18, will stand idle, the

shaft 12, turning within said pinion 13, andV the clutch sleeve 26, turning within the bearing member 30. The plunger 34, in thev meantime, will rest uponY the cam block 41, on the large gear 18, in its stoppedV position,

thus holding the clutch sleeve 26, andthe f clutch teeth`27, thereof, out of driving engagement with the clutch teeth 14, on said pinion 13. Therefore, when the trip 'lever 38, is moved outwardly, in a manner hereinafter described, out of the notch 37, in the plunger 34', it allows the bearingmember 30,

and the clutch sleeve 26, tobe moved inl vvardlyV into driving engagement withvk the clutch teeth 14, by means ofthe spring 29, whereupon said pinion 13, being again locked to the shaft 12, drives the large gear 18, moving the cam block on its inner face from under the plunger 34. Said plunger 34, is again thrust outwardly in its normal position by its spring 35, and the machine continues to run until the gear 18, has made one complete revolution and the main cam block- 41, rthereon has again en aged said plun er 34, and again movedt e bearing mem n30, and the clutch 26, out of driving engagement with the clutch teeth 14, of the pinion 13.

Thus it will be seen that the constantly driven shaft 12, is intermittently, by means of ythis clutch mechanism just described, thrown into and out of driving engagement with the principal operating mechanism of the machine, said connection being from the clutch pinion 1.3., to the gear 18, on the shaft 16,on which shaft is also mounted the gears 17, 19, 20, 21 and 22, the shaft 23, being intermittently driven by its inion 24, which is intermittently driven by tlhe lock gear 17 from which shaft. 23, the lar e gear 8, is driven through the pinion 25, t us intermittentl turninlg the wheel structure 6, forwar y ste ste I will'nelirt 5descll'ibe the weighing mechanism b means of which the matter to be wrappe is weighed out in predetermined amounts, together with the means for feeding this matter to the weihing mechanism,

and also the means for fee 'ng the wrapping paper into position to receive said matter from the wei hing mechanism.

As my ma ine is especially designed for weighing and wrapplng raisins, I have shown mechanism for separating the raisins as they are fed into the weighing mechanism. This mechanism is shown in Figs. 4, 5 and 6. The raisins are fed from any suitable hop er, or container, through a series of revo ving separating fingered members 42-42, all driven together by means of a pulley 43, and connected to each other by means of sprocket wheels 44-44, over which runs a sprocket chain 45. From the fingered members 42, the raisins are fed through on to a traveling belt 46, running over suitable rollers 47 and 48, supported at one end upon a standard 49, upon the machine proper, and at its other end upon an independent standard 50, as clearly illustrated. Said belt 46, is driven by means of a sprocket chain 51, and a sprocket wheel 52, upon the outer end of the shaft on which the roller 47, is mounted. As the raisins Vare carried forwardly on the top lap of the belt 46, in the direction indicated by the arrow, Fig. 5, between the side pieces 53, they are discharged as at 54, into the weighing box, or container, 55. Said weighing boxl 55, is pivotally supported between the outer ends of two arms 56-56, secured to a shaft 57. Mounted upon said shaft 57 is a short arm 58, having a pivoted short trip finger 59, adapted to underlie the weighted balance lever 60, pivotally mounted at its opposite end at 61, upon a shaft 62, and provided with an adjustable weight 63, adapted to be secured in place on said lever 60, b means of a thumb screw 64. The trip nger 59, pivoted to the short arm 58, is capable of being turned upwardly on its pivot, but can not be turned downwardly on said ivot. Therefore, as the raisins fill the weig ing box 55, and said box descends under its weight, the short arm 58, and its trip finger 59, move upwardly together, lifting the weighted lever 60, thus allowing the weighing box 55, to descend. Also secured to the shaft 57, intermediate its ends, is a rod 65, on which is a suitable balance weight 65, adapted for balancing the weighing box 55, and its mechanism when the same is empty. Secured to the opposite sides of the weighin box 55, are ears 66-66, to which are pivotally attached at their upper ends operating arms (B7-67, said operating arms being attached at their lower ends to slide bottom pieces 68-68, slidably mounted in guide frames 69-69, carried by said weighing box 55, near its bottom, which bottom pieces are adapted to be moved into and out of said weighing box to receive, support and discharge the contents of said weighing box.

Referring to Figs. l and 2, there is shown mounted on the side of the weighing box 55, a rocker lever 70,havinga cam finger 71, adapted when said weighing box descends to engage a cam block 72, mounted upon the top of the frame member 3, said rocker lever 70, being connected at its opposite ends b means of links 73-73, with the arms 6 67, whereupon as said weighing box 55, descends and said cam finger 7l, engages the cam block 72, said rocker arm 70, is rocked, so as to move the levers 67-67, outwardly and away from the box 55, thus operating to open the bottom pieces 68--68, to allow the contents to drop out on to the wrapping paper, above the wrapping pocket, ready to receive the same, in a manner hereinafter described. The arms 67-67, and the bottom pieces 68--68, are drawn inwardly to close the bottom of said box, by means of a coiled spring 74, secured at its opposite ends to short arms 75--75. connected at their upper ends, as at 76-76, to the pivot shafts on which the arms 67-67. are mounted. Also mounted on one side of the box 55, is a bearing ring 77, adapted toA move down between upstanfiing guide fingers 78, on a base 79, secured to the top of the frame 4. This prevents the box from tipping as it moves downwardly with its load.

A shut-ofi' gate 80, is pivotally mounted. as at 81, between the side members 53, of the mechanism for feeding the raisins into the `box 55, said shut-off gate being operated by'means of a bell crank 82, one armvof which is connected with a spring 83, for

normally moving said gate open, inthe posi; Y

u freely along the side of the weighing box 55, where it is provided with a pin 85,`

adapted to be engaged by the box supporting arm 56, as it descends', thus operating to close the shut-off gate 80, and prevent the further feeding of raisins therethrough until the weighing box is again` lifted and the gate opened by means of its spring 83.

Mounted across the top of the machine,v

directly above shaft 57, is a shaft 86,in the middle of which is mounted a sleeve 87, projecting from which is a yoke-like member 88, shown in top plan view in Fig. 2, and in section in Fig. 5. Said yoke-like member projects immediately above the arm 58, and is adapted when turned downwardly to engage said short arm 58, and to rock the shaft 57 for the purpose of raising the weighing box 55, after it has discharged its load.

connected therewith the upper end of a pitman rod. 90, the lower end of which is connected with a crank disk 91, on the inner face of which is a gear 92, seen in Figs. 1, 2 and 3, which gear is in mesh with the large gear 20, on the shaft 16. f

Also mounted across the top of the frame members 3 and 4, and directly under the shaft 57, is a shaft 93, having mounted in its middle portion an arm 94, and on its end a crank arm 95, connected with which is a pitman 96, clearly shown in Fig. 1, the lower end of which pitman is connected with Y an arm 97, on a shaft 98, mounted between Y engages the arm 94, thus rocking shaft 93, I

and through the parts 95, 96 and 97, also 60 the upright frame members 2 and 3, and provided near the frame member 2, with a downwardly depending operating arm 99,

adapted to engage and operate the trip lever 38, of the clutch mechanism, whereby to trip the clutch and allow it to be thrown into operating position, as hereinbefore described. Mounted on the shaft 57, between the arms 56-56, which carry the weighing box 55, is an operating arm 100, shown in dotted lines in Figs. 1 and 5, and in plan in Fig. 2.v This arm is Vdirectly above the arm 94, on the shaft93, whereby as weighing box 55', descends with its load the arm 100, is rocked downwardly with it until it rocking shaft 98, so as to move the downwardly projecting arm 99, thereon, into engagement with the trip lever 38, for tripping the clutch, as above referred to, thus starting the machine as the` matter to be Mounted on one of the outer endsr of said shaft 86, is a crank arm 89, having I into the machine, and for cutting it off inV .proper lengths for each package.V Support? ing brackets, as 101-101, are `mounted on the frame members, as clearly shown 1n Figs. 1 and 5, between which a roll of wrapping paper 102,A indicated in dotted lines,`isY

supported. From the roll 102, thefpaper is fed under a roller 103, mounted between the frame members 3 and 4, thence forwardly between an upper roller 104, and a lower etY roller 105, thel latter of which is provided ,i

Ywith soft feeding rings 106, saidfeed rollers 104 and 105, being mounted upon shafts 107v and 108, respectively, on the outer ends of whichl are meshing gears 109 and 110, seen in Fig. 1. Mounted upon the oppositel end of shaft 108, is a gear 111, having a smoothed locking face 1.12, shown in lockedengagement .with theinner gear 21, as seen in Figs. 3 and 4, the gear 21, beingdirectly' behind the gear'22, asy shown in- Fig. 4, some of the teethof gear 21, being seen projectingfrom behind the gear 22, yat the lefthand side thereof. Thus as shaft 16, is revolved, the gear 21, intermittently turns the gear 111, the shaft 108, andthe feedrolleis i f 104 and 105, feeding a quantity of the wra pingl paper forwardly directly under tllfe weighing box 55, and above the lopening 10, in the wheel structure casing, as clearly shown in Fig. 5, said lpaper bei-ng indicated in position lby a dotted line running from thel roll 102, under the roll 103". Y

A knife113, isfpifvotally mounted, as-at 114, and is adapted to be closed down across the `paper at the .point 115, Fig. 5, 'thus cutting off a portion of the paper resting under the weighing box 55.A Said knife, at its hinged end, has a short projecting arm 116, to which is connected an operating pitman 117, the'lower end lof which is lconnected to.

the end of a rocker arm 118, shown in dotted lines in Fig. 1, and seen in top edge view in Fig. 2, said arm projecting adjacent the Y inner face of the large gear 19, on which is mounted a trip roller 119, adapted with `each revolution to engage said trip lever 118, and through the connections inst de scribed intermittently operate the knife 113, which shears the paper. The piece of wrap-l ping paper thus cut, rests directly undcr-V g neath. the weighing box 55', so that as said weighing box receives a pre-determined y amount of raisins, orl other matter to be wrapped, and moves downwardly and discharges its contents, in the manner .herein-V before described, said contents ycauses thev wrapping paper to 'sink throughl the 'open-V ing 10, in the frame and into the uppermost I pocket 6a, inthe wheel structure 6, as will be clear from Fi 5. Referring to Fig. 7, it will be noted t at there are two inclined side walls 120--120, depending from the under side of the top plate 121. These serve to hold the opposite sides of the paper in an upwardl inclined position as it sinks with its weig t into pocket 6, thus preventing the raisins from running out, the wrapping paper, as it sinks into the pocket 6, assuming the form shown in Fig. 11. At this stage of the proceedings, the large gear 22, Fi 4, which has been up to this point in loc ed sliding engagement with a small gear 122, turns said gear 122, which is provided on its outer face with a crank disk 123, having thereon a crank pin 124, to which is connected a pitman 125, the opposite end of which is connected, at at 126, with a segment lever 127, pivotall mounted at its lower end, as at 128, in t e side member 4, and at its upper end provided with a se mental arcY 127, having the two gear-loch ing surfaces 129 and 130, and the teeth 131. Pivotally mounted at the opposite sides of the opening 16, in the top of the wheel structure casing, are two folding wings 132 and 133, shown in section in Fi 5 and in dotted lines in Fig. 4. The s aas on which said folding wings are mounted, are provided at their outer ends with lock gears 134 and 135, adapted to have operating and holding engagements with the segmental arc 127, so that as said segment lever 127, is moved, first to the right, it causes the folding wing 132, to be folded over in the direction indicated b the arrow, Fig. 4, which folds oneiside of t e paper down on to the contents in the pocket 6", and as said segmental lever 127, moves back to its middle position, said folding wing is returned to its normal position, shown in dotted lines, and the continued movement of the segment lever 127, to the left operates to move the folding wing 133', thus folding the opposite side of the pa r down atwise on to the contents, the pac age now assuming the form shown in Fig. 12. The folding wings 132 and 133, are successively moved, in the order mentioned, to fold rst one side of the paper and then the other side, the gear 122, having a locked sliding engagement with the gear 22, with the parts in the position shown in full lines, Fig. 4, until the next pocket in the wheel structure has been moved up into receiving position, and the operation just described is repeated. As the folding wing 133, raises, the wheel structure 6, is given a one-eighth turn in the direction indicated y.by the arrow, Fig. 5,

:this being accomplished by the engagement of the pinion 25, with the large gear 8, which is mounted on the same shaft 5 with said wheel structure. The pinion 25, as before described, is mounted on the shaft 23, on which is also mounted the lock inion 24, which turns said shaft 23, a hal turn with each full revolution with said gear 17, as hereinbefore described.

With the top sides of the wrapping` paper folded over in the manner shown in 1g. 12, the wheel structure 6, turns an eighth of a turn, in the direction indicated by the arrow, Fig. 5, bringing said partially wrapped package into a position between two endfolding wings 13G-136, which are hingedly mounted in the frame structure, as at 137- 137, and in positions at the opposite ends of the wrapping pockets in the wheel structure 6, as said pockets are moved intermittently and successively between said bottom folding wings 136-136. Said bottom end-folding wings are operated by means of links, as 138, each being connected at one end, by means of a knuckle 139, to a short arm 140, mounted on the sleeve portion of each of said wings, each of said links, 138, being connected at its upper end with a short crank arm 141, mounted on a shaft 142, supported in bearing brackets 143-143, mounted upon the frame, or closure, for the wheel structure, as clearly shown in Fig. 5. Mounted upon the middle of said shaft 142, is a crank arm 144, connected with which is a link 145, provided on its opposite sides with a pair of rollers 146-146, said link 145, being connected at its lower end with the upper orton of a bell crank 147, shown 1n detail in Fi 18, the lower part of said bell crank 147, eing connected by means of a link 148, with a crank arm 149, the outer end 150, of said crank arm being connected to a spring 151, and anchored at its lower' end to the base 1, of said machine, as at 152. Mounted on the shaft 16, for `engagement with the rollers 146-146, mounted on opposite sides of the link 145, is a double cam member 153, adapted to engage said roller as it revolves in the direction indicated by the arrow, Fig. 5, and to force said link 145, inwardly, thereby rocking the shaft 142, and through the arms 141--141, and the links 138-138, closing the folding wings 136-136, at the opposite ends of the pocket inwardly, which folding wings fold the ends of the wrapping paper inwardly from the positions shown in Fig. 12, to that shown in Fig. 13. The movement of said link 145, by the cam 153, also rocks the bell crank 147 and through the link 148, the arm 149, which operates to partially turn the beveled gears 154-154, mounted upon shaft 155, upon which the bell crank 147, is mounted, and also the gears 156-156, mounted upon the shaft 157, upon which the arm 149, is mounted. The gears 154-154, are in mesh with beveled gears 15S-158, through which are slidably mounted two shafts 159-159, which shafts 159 are feathered to their gears dotted linesin Figs. 3 and 5. LThe gearsY 158-158,v and are provided -on their inner ends with folding fingers 160-160, shown in 156-156, mesh with the gears 161-161,

mounted on shafts 162-162, similar to the shafts 159, which shafts 162-162, are featheredto their gears 161, whereby to slide therethrough, and are provided on their inner ends with folding fingers 163-163,

shown in dotted lines in Figs. 3 and 5, whichv that these fingers 160 and 163, can operate upon the opposite ends of the package, in the manner just described, leaving the package in the formshown in Fig. 14. In order to simultaneously and intermittently move said shafts 159 and 162, inwardly-through the. gears 158 and 161, so as to move said folding fingers 160 and 163, inwardly, into positions opposite thegopposite en ds ofthe Vpackage' lpocket 6c, as indicated 1n dotted lines in Figs. 3 and 5, I provide connecting bars 165-165, connecting the shafts 159 with the shafts 162. Pivotally connected at their lower ends to the middles of said bars 165- 165, Vare two forks 166-166, pivotally mounted near their upper ends upon a short shaft 167, having its bearings in the' opposite frame members 3 and 4, each of said forks being provided at its upper end with two'short arms`168-168, between which is mounted a roller 169, said rollers being "adapted to engage cams170-170, mounte upon the shaft 16, just inside the frame members 3 and 4, as clearly shown in Fig. 3, and one of which is also seen on shaft 16, in Fig. 5, this side of the double cam 153.

Thus it will be seen that as said shaft 16, is intermittently revolved, in the manner hereinafter described, it operates through the double cam 153, to operate thel folding wings 136-136, at the ends of pocket 6b, in

the wheel structure 6, and also the folding' fingers 160 and 163, at the ends of pocket 6, folding the end of the package in pocket 6b, from the position shown in Fig. 12, to

the position 'shown in Fig. V13, and simultaneouslyfolding the sides of the ends of the next .package in advance,-in. pocket 6,

from the condition shown in Fig. 13, tothe condition shown in Fig. 14. Just precedingy the folding of the sides of the ends, however, at pocket 6C, the cams 170-170, rock the 'forks 166-166, so as to thrust the shafts 159 and 162 inwardly, so thatfwhen the double camY 153, moves thelink 145, said folding fingers can be operated in the manner Ajust described.

Formed as apart of the sleeve on which the crank arm 149, isv formed, is a gear segment 171, which is operated with the movement of the arm 149, to which is connected the operating link 148. Mounted between the frame members 3 and 4, is a shaft 172, Y

provided in its middle with a gear 173, adaptedto be intermittently operated by the gear segment 171. Mounted upon they opposite ends of the shaft 172, are beveled gears 174-174, which mesh` with beveled gears 17 5-175, upon the upper ends of shaft 176, Fig. 5, which operate folding wings 177- 177, shown in Figs. 3 and 5, these folding wingsV beingl so positioned that whenA a 'pocket of the wheel structure reaches thatv point, as 6Fl, the package is "in the form .shown in Fig. V14, whereupon the folding wings 17 7 atthe opposite ends of the pocket 6d, Fig. 5, fold the top folds of the package-V into the positions shown in Fig. 15. VThus the wrapping paper is folded aboutA the mattei' beingV wrapped, step by step, as shownv in soV` Figs. 12,13, 14 and 15, as the package is successively advanced through the positions indicated by the pockets 6, (3",6c and 6, Fig. 5. Vith the next operation of the machine the folded package is moved to the position of pocket 6e. It will be understood, of course, that there isapackage in each of the ypockes 6, 6", 6C, 6d and 6, being operated upon, simultaneously, the folding wings 132 and 133,V folding the wrapping paper over the package into theposition shown in Fig. 12, immediately preceding the partial rotation of the wheelr structure 6, and during the next stop the bottom end folders 136, the side end folders 160-163 and the top; end folders 177, are all simul- Y taneously operated through the action-of the Y doublecam 153. In order to make a quick return of all of these folding members, the

spring 151, Vis. shown attached to the arnr Y 150, so that as soon as the acting portion of theA doubley cam,` 153, passes Vthe rollers 146-146, said parts are all drawn down.V quickly by said spring 151, to their normal positions, with the folding members open-.to give clearance for the next partial revolution of the wheel structure 6.

VI willnow describe the mechanismV by 'Y means of which the foldingy packages are 'discharged from the down pocket, that is,

the pocket occupyingthe position of pocketv 6e, in Fig. 5. Referring to Figs. 1, 3 Vand 7, there is mounted on vthe base 1, ofthe'ma- Y chine, a box-like slide casing .178, within v which is 'a sliding plunger 179, also ofv boxlikeconstruction, having its top middle portion open lengthwise thereof, and provided in its'bott'om with a longitudinally extend ing rack 180. Mounted between the upright frame members 2 and 3, Fig. 3, is a shaft 181, provided in its middle portion with ya gear 182, adapted to be engaged by a segment 183, formed upon the lower end of a pendulnmalike lever 184, pivoted at its upper end on the shaft 16, 'said lever 184, havmg a longitudinally extending roller slot 185, within which works a roller 186, on a disk 187, which fdisk is mounted upon the outer end of ashaft 188, secured at its inner end to the upright frame member 3, and provided with a' spacing sleeve 189.

' Also mounted on said shaft 188, at the end of said sleeve, is a gear 190, which is secured to, or is made as a-part of, said disk 187, and is in position to mesh with and be driven by the large gear 19, mounted on the shaft 16, whereby `es sai-d segment-lever 184, is oscillated by the turning of said disk 187, it operates through the gear 182, to turn the shaft 181. Mounted on the inner end of the shaftv 181, is a'beveled gear`191, adapted to mesh with a beveled gear 192, on a shaft 193, provided at its opposite end with a gear 194, which meshes with and operates the rack 180, in the sliding plunger 179, said sliding plunger being adapted to be moved through the down pocket, occupying the position of the pocket 6, in Fig. 5,'whereby said plungerforces the wrapped Ypackage out at the opposite side of said pocket into the` open end of a box-like receptacle 195, pivotally mounted, as at 196, Fig. 7, and provided with a handle 197, whereby it can e tipped to the position shown in dotted lines, Fig. 7, to discharge the wrapped package therefrom.

Mounted in the base, directly below the down pocket, that is, pocket 6*, Fig. 5, is a platform-like member 198, yieldingly supported on springs 199, which operate to compress the packages as they come to this position, and before they are discharged from the machine.

The use and operation of my invention may bebriefly `described as follows:

The raisins are fed through the finger members 42-42, in the feeding mechanism, for the purpose of breaking them up before they are delivered to the feed belt 46, by meansof which they are carried to the weighing receptacle 55. When a suiiicient quantity of raisins has been discharged into the receptacle 55, to overbalance the weight 63, said receptacle descends with its weight, the-holding finger 59, slipping from under the weighted-arm 60. As said receptacle descends, the cam `finger 71, which operates the rocker 'lever 70, on the side of said receptacle, engages with the cam block 72, and is` operated for o ing-'the bottom members8-1-i-68, of sai receptacle, for automatically discharging the raisins from said receptacle. 'In the meantime ,the end of the wrapping pa r has been fed forwardly underneath t e receptacle and above the opening 10, through the casing 9, which contains the wheel structure having the wrapping pockets therein. As the matter is discharged from said receptacle it sinks with the wrapping paper into the uppermost pocket, which would be 6, Fi 5, assuming the form shown in Fig. 11. rhe knife 113, in the meantime has been operated for cutting olf the quantity of wrapping paper required for the package. At this point the machine iS automatically thrown into gear, in the manner described, by the tripping of the clutch lever 38. The folding members 132 and 133, are automatically operated in the order mentioned by the mechanism, hereinbefore described, folding the paper over the matter into the form shown in Fig. 12. The wheel structure 6, rotates an eighth of a turn, bringing the pocket 6, into the position occupied by the pocket 6, Fig. 5, whereupon the folding members 136-136, at opposite sides of the wheel structure are operated to fold the bottom ends of the package into the form shown in Fig. 13. The package in pocket 6, is also being operated upon as is the package in the pocket 6d. The package in the pocket 6, is having the sides of the ends of the wrapper folded into the position shown in Fig. 14, while the package in the pocket 6d, is having the tops of the ends folded into the position shown in Fig. 15. The package in the pocket 6, is being automatically discharged from the pocket. Thus all of the packages in the pockets 6, 6, 6, 6d and 6, are being operated upon simultaneously. A completely wrapped package is ejected from each pocket as it pmes to the position occupied by pocket 6,

It will be seen, therefore, that the machine automatically separates the raisins, fee-ds them to the weighing mechanism, discharges them on to wrapping paper which is automatically fed into place to receive the same, and automatically wraps the raisins into a compact uniform package and discharges it ready for the box or carton into which it is placed for the market.
